How to retrieve the data from MDM hierarchy table using MDM Java API

Question

Hi,
I had a hierarchy table in MDM. This table had some column say x. I want to retrieve the values of this x column and need to show them in a drop down using MDM Java API.
Can anyone help me to solve this?

Hi,
Here is your code...
TableId Hier_TId = repository_schema.getTableId(<hierarchy table id>);
java.util.List list = new ArrayList();
ResultDefinition Supporting_result_dfn = null;
FieldProperties[] Hier_Field_props =rep_schema.getTableSchema(Hier_TId).getFields();
LookupFieldProperties lookup_field = null;
TableSchema lookupTableSchema = null;
FieldId[] lookupFieldIDs = null;
for (int i = 0, j = Hier_Field_props.length; i < j; i++) {
if (Hier_Field_props<i>.isLookup()) {     
                              lookup_field = (LookupFieldProperties) Hier_Field_props<i>;
     lookupTableSchema =repository_schema.getTableSchema(lookup_field.getLookupTableId());
                              lookupFieldIDs = lookupTableSchema.getFieldIds();
     Supporting_result_dfn = new ResultDefinition(lookup_field.getLookupTableId());
     Supporting_result_dfn.setSelectFields(lookupFieldIDs);
     list.add(Supporting_result_dfn);
com.sap.mdm.search.Search hier_search =new com.sap.mdm.search.Search(Hier_TId);
ResultDefinition Hier_Resultdfn =     new ResultDefinition(Hier_TId);
Hier_Resultdfn.setSelectFields(rep_schema.getTableSchema(Hier_TId).getDisplayFieldIds());
ResultDefinition[] supportingResultDefinitions =
(ResultDefinition[])list.toArray(new ResultDefinition [ list.size() ]);
RetrieveLimitedHierTreeCommand retrieve_Hier_tree_cmd =
new RetrieveLimitedHierTreeCommand(conn_acc);
retrieve_Hier_tree_cmd.setResultDefinition(Hier_Resultdfn);
retrieve_Hier_tree_cmd.setSession(Auth_User_session_cmd.getSession());
retrieve_Hier_tree_cmd.setSearch(hier_search);
retrieve_Hier_tree_cmd.setSupportingResultDefinitions(supportingResultDefinitions);
try {
     retrieve_Hier_tree_cmd.execute();
} catch (CommandException e5) {
          // TODO Auto-generated catch block
          e5.printStackTrace();
HierNode Hier_Node = retrieve_Hier_tree_cmd.getTree();
print(Hier_Node,1);
//method print()
static private void print(HierNode node, int level) {
if (!node.isRoot()) {
     for (int i = 0, j = level; i < j; i++) {
          System.out.print("\t");
     System.out.println(node.getDisplayValue());
HierNode[] children = node.getChildren();
if (children != null) {
          level++;
for (int i = 0, j = children.length; i < j; i++) {
print(children<i>, level);
//end method print()
